We have this on display under a microscope at VCF Mid-Atlantic museum.

It is strangely constructed to my eye.
no lead frame or bond wires.
Its build ON the leadframe.
Its symmetrical, appears to be a dual something.

That lead-frame is really weird.
It seems to be some sort of flip-chip, but the leads don’t even line up 
from one side of the chip to the other!
Never seen anything like it.
The only other thing I would GUESS is that this is some sort of analog 
IC, probably bipolar.
